Try this if its a windows server:
<% For Each name In Request.ServerVariables %>
<p ><%= name %><%= Request.ServerVariables(name) %></p>
<% Next %>
If you don't know whether the server supports asp or php try the write commands in each lingo (you have to name the doc correspondingly, ie .asp or .php):
<h1><%response.write("kuken")%><? echo"balle";?></h1>
Good luck,
